IMPROVEMENT IN FLOUR-BOLTS.

Specification forming part of Letters Patent No. 56,887, dated August 7,1866.

7 To all whom it may concern:

Be it known that I, J. O. BLYTHE, of Perry, Wyoming county, and State ofNew York, have invented a new and useful Improvement in Flour- Bolts;and I do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the same, reference being had to the accompanying drawings,forming part of this specification, in which Figure 1.is a longitudinalsection of my improved flour-bolt taken through the line w 00, Fig. 2.Fig. 2 is a cross-section of the same taken through the line y y,Fig. 1.

Similar. letters of reference indicate like parts.

My invention has for its object to furnish an improved flour-bolt, bymeans .of which flour may be bolted faster and more evenly than with thebolt nowin common use; and it consists in the combination of partitionsand hoops with the arms and ribs and cloth of a flour-bolt, soconstructed and arranged that a space may be left between the said ribsand cloth between each pair of hoops, so that the flour may be incontact with the cloth all around the bolt, as hereinafter more fullydescribed.

A is the bolt-shaft, to which motion is com- B are arms, which projectfrom theshaft in the usual way, and at distances apart such as willsufficientlysupportthe ribs 0. These ribs extend lengthwise of thebolt,and are securely attached to the ends of the arms B. Around the bolt, atsuitable distances apart, are hoops D, which are attached to the ribs 0by screws, so as to be removable when desired. Between the hoops Dtheout'erparts of the ribs 0 are cut away, as shownin Fig. 1, so thatbetween the hoops the flour may have free access to the bolt-cloths allaround the bolt, and thus be prevented from clogging or banking upbehind the ribs and interfering with the efficiency of the bolt and therapidity of its operation. This same thing may be accomplished .bymaking the hoops D of such a thickness as will leave a sufficient spacefor the passage of the flour bet-ween the edges of the ribs 0 and thebolt-cloth.

E are partitions attached to the arms B, and V in this way will do asmuch work as a twentyfour-foot bolt constructed in the old way.

I design to cover the space between each pair of hoops with cloth of adifferent number, beginning at the head of the bolt with the coarsestnumberas, for example, with No. 8-and following with the finer numbersin regular order. The distance of the hoops apart will vary with thenumber of kinds of cloth desired to be used. The cloths can be removedfrom a bolt constructed in this Way, when desired, by simply removingthe screws which attach the hoops D to the projecting parts of the ribs0.

I claim as new and desire to secure by Letters Patent V The combinationof the partitions E and hoops D, either or both, with the arms B, ribs0, and cloth of a flour-bolt, when the said parts are constructed andarranged substantially as herein described,.and for the purposes set
